Hi!!!, i used to be home schooled. IT WAS THE WORST. I've had to go through what your going through right now for 2 years. I'm in the 8'th grade. and i've been wanting to meet new friends.
Time taken by Jami to mow 1/6 acres is 8 minutes=8/60=2/15 hours.
Rate at which Jami is mowing will be:
rate=(number of acres)/(time)=(1/6)/(2/15)
=1/6÷2/15
=1/6×15/2
=5/4 acres/hour
=1.25 acres/hour
From above calculations we conclude that Jami cannot mow 1.5 acres in 1 hour
The vertex would be (-2,4)
When x = -3 y = -5
When x = -1 y = -1
When x = 0 y = 1
When x = 2 y = 5
